Description

Technical Field

[0001] This utility model relates to the field of dyeing, and in particular to a nozzle and a dyeing machine. Background Technology

[0002] The dyeing machine is equipped with nozzles, each including a nozzle core. The fabric moves from one end of the nozzle core to the other. During this process, dye liquor is sprayed onto the fabric through the spray channel of the nozzle core, dyeing the fabric. The spray channel 300 is a long and narrow channel formed by the upper nozzle core 100 and the lower nozzle core 200, as shown below. Figure 1 As shown, the existing upper nozzle core 100 and lower nozzle core 200 are connected by a connecting piece 400. During manufacturing, the upper nozzle core 100 and lower nozzle core 200 are machined separately and then welded to the connecting piece 400. This manufacturing method lacks radial positioning and suffers from significant axial errors due to welding deformation, resulting in an uneven spray channel and low precision. To ensure a uniform spray channel and improve precision, tooling, fixtures, and current adjustment are required, but the precision remains low. However, the precision of the spray channel has a significant impact on the dyeing effect. Low precision in the spray channel leads to uneven application of dye to the fabric, easily causing fabric twisting, resulting in creases and uneven dyeing, greatly affecting the dyeing effect.

[0004] The technical problem to be solved by this utility model is to provide a dyeing machine equipped with the nozzle.

[0005] To solve the above-mentioned technical problems, the present invention provides a nozzle, including a nozzle core, wherein the nozzle core includes a first nozzle core component, a second nozzle core component, and a positioning component, wherein a limiting ring is provided on the outer side wall of the first nozzle core component; the positioning component is disposed above the second nozzle core component and is fixedly connected to the second nozzle core component;

[0006] The positioning component has an installation port; the first nozzle core is inserted through the installation port and mounted on the positioning component, and the limiting ring is inserted inside the installation port and abuts against the inner wall of the installation port; the first nozzle core is inserted inside the second nozzle core, and a liquid spraying channel is formed between the first nozzle core and the second nozzle core.

[0007] As an improvement to the above solution, the first nozzle core, the second nozzle core, and the positioning element are coaxially arranged;

[0008] The first nozzle core includes a first guide portion passing through the mounting port, and the limiting ring is disposed on the outer side wall of the first guide portion; the second nozzle core includes a second guide portion, and the included angle between the axes of the first guide portion and the first nozzle core is equal to the included angle between the axes of the second guide portion and the second nozzle core.

[0009] As an improvement to the above solution, the first nozzle core also includes a support connection portion disposed at the top of the first guide portion, the support connection portion being mounted on the positioning member.

[0010] As an improvement to the above solution, the outer edge of the positioning member and the support connection are fixedly connected.

[0011] As an improvement to the above solution, the height of the first guide portion is greater than the distance between the top of the second guide portion and the top of the positioning member.

[0012] As an improvement to the above solution, the nozzle core further includes a connecting member, and the positioning member and the second nozzle core are fixedly connected by the connecting member.

[0013] As an improvement to the above solution, the diameter of the mounting port is equal to the outer diameter of the limiting ring.

[0015] As an improvement to the above solution, the nozzle housing is provided with a dyeing liquid chamber and a support base, and the support base is provided with a material passage chamber.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0026] See Figure 2-5 This utility model discloses a nozzle, including a nozzle core, the nozzle core including a first nozzle core 1, a second nozzle core 2 and a positioning member 3, the outer side wall of the first nozzle core 1 is provided with a limiting ring 12; the positioning member 3 is disposed above the second nozzle core 2 and is fixedly connected to the second nozzle core 2.

[0027] The positioning member 3 is provided with an installation port 31; the first nozzle core 1 passes through the installation port 31 and is mounted on the positioning member 3, the limiting ring 12 passes through the installation port 31 and abuts against the inner wall of the installation port 31; the first nozzle core 1 is inserted into the second nozzle core 2, and a liquid spraying channel 5 is formed between the first nozzle core 1 and the second nozzle core 2.

[0028] The nozzle core of this invention is equipped with a positioning component, which is fixedly connected to a second nozzle core component, thus fixing their relative positions. A first nozzle core component is then mounted on the positioning component, further fixing their axial positions. Furthermore, the mounting port and a limiting ring work together to fix the radial positions of the first nozzle core component and the positioning component, meaning their radial positions are also relatively fixed. Therefore, both the first and second nozzle core components are limited in both the axial and radial directions, ensuring a uniform and precise spray channel between them, resulting in uniform spray force, uniform dyeing, and a good dyeing effect.

[0029] Preferably, the first nozzle core 1, the second nozzle core 2, and the positioning member 3 are coaxially arranged; for example... Figure 2-5 As shown, the first nozzle core 1 includes a first guide portion 11 passing through the mounting port 31, and the limiting ring 12 is disposed on the outer side wall of the first guide portion 11; the second nozzle core 2 includes a second guide portion 21, and the angle formed by the axis of the first guide portion 11 and the axis of the first nozzle core 1 is equal to the angle formed by the axis of the second guide portion 21 and the axis of the second nozzle core 2, that is, the first guide portion 11 and the second guide portion 21 are arranged parallel to each other. Since the first nozzle core and the second nozzle core are coaxial, that is, the axes of the first nozzle core and the second nozzle core are on the same straight line, and the angles formed by the first guide portion and the second guide portion with the axes of the first nozzle core and the second nozzle core are equal respectively, that is, the inclination angles of the first guide portion and the second guide portion are the same, thereby ensuring that the liquid spray channel formed between the first guide portion and the second guide portion is uniform and has high precision.

[0030] Specifically, such as Figure 3-4 As shown, the first nozzle core 1 further includes a support connecting portion 13 disposed at the top end of the first guide portion 11, and the support connecting portion 13 is mounted on the positioning member 3. The positioning member supports and positions the first nozzle core, ensuring a stable position between the first nozzle core and the second nozzle core, thereby guaranteeing the accuracy of the spray channel. The support connecting portion is mounted on the positioning member, and the first guide portion passes through the mounting port and inserts into the second guide portion, forming a spray channel between the first guide portion and the second guide portion.

[0031] It should be noted that, as Figure 2 ,4 As shown in Figure 5, both the first nozzle core 1 and the second nozzle core 2 are hollow structures with through-end faces, thus forming the material passage 6 of the nozzle core. The fabric moves within the material passage, specifically entering the first nozzle core 1 from the top and moving towards the second nozzle core 2. During this movement, the dye liquor is sprayed from the spray channel into the material passage, i.e., onto the fabric, thus dyeing the fabric.

[0032] The height of the first guide part 11 is greater than the distance between the top of the second guide part 21 and the top of the positioning member 3, ensuring that the first nozzle core 1 is mounted on the positioning member 3 and the bottom of the first nozzle core 1 is inserted into the second nozzle core 2, thereby forming the liquid spraying channel 5.

[0033] Preferably, such as Figure 2-3 As shown in Figure 5, the nozzle core also includes a connecting member 4, and the positioning member 3 and the second nozzle core 2 are fixedly connected by the connecting member 4. One end of the connecting member 4 is connected to the bottom of the positioning member 3, and the other end is connected to the outer wall of the second nozzle core 2. The connecting member fixes the relative positions of the positioning member and the second nozzle core, thereby ensuring that the relative positions of the first nozzle core and the second nozzle core are fixed.

[0034] Preferably, the diameter of the mounting port 31 is equal to the outer diameter of the limiting ring 12, that is, the mounting port 31 and the limiting ring 12 are the same size. The limiting ring 12 and the inner sidewall of the mounting port 31, i.e. the positioning member 3, abut against each other to ensure that the first nozzle core and the positioning member are relatively fixed in the radial direction. This ensures that the first nozzle core and the second nozzle core are relatively fixed in the radial direction, avoiding the relative displacement in the radial direction of the first nozzle core and the second nozzle core when they are connected and fixed, which would affect the accuracy of the spray channel and further ensure the accuracy of the spray channel.

[0035] Preferably, the outer edge of the positioning member 3 and the support connection portion 13 are fixedly connected. More preferably, the outer edge of the positioning member 3 and the support connection portion 13 are welded. Welding at this location will not affect the accuracy of the spray channel and can fix the first nozzle core and the second nozzle core.

[0036] During manufacturing, the second nozzle core and the positioning component are welded to the connecting component before machining. This post-weld machining avoids welding deformation. The first nozzle core is directly machined. Furthermore, machining ensures the fitting accuracy of the mounting port and the limiting ring, the height of the first guide portion, and the accuracy of the distance between the top of the second guide portion and the top of the positioning component, thus guaranteeing both axial and radial errors and ensuring the accuracy of the spray channel. Finally, the first nozzle core is installed on the positioning component, and welding is performed on the outer edge of the positioning component and the support connection. Welding on the outer edge of the positioning component does not affect the accuracy of the spray channel.

[0037] Furthermore, such as Figure 2 As shown, this utility model also includes a nozzle housing 7, in which the nozzle core is installed. The nozzle housing 7 has a liquid inlet 71, and the nozzle core has a material passage 6. The liquid inlet 71, the spray channel 5, and the material passage 6 are sequentially connected. The material passage extends through both ends of the nozzle core. The fabric enters the material passage and moves from one end of the nozzle core to the other. The dye liquor flows into the nozzle from the liquid inlet and is sprayed onto the fabric through the spray channel to dye the fabric.

[0038] Preferably, the nozzle housing 7 is provided with a support base 73, and the support base 73 is provided with a material passage cavity 74, which communicates with the material passage channel 6. Figure 2 As shown, the fabric enters the material passage from above the nozzle core, then enters the material passage cavity, and finally exits from the bottom of the nozzle housing. The dye liquor flows into the material passage cavity through the inlet, and then is sprayed onto the fabric moving in the material passage and material passage cavity through the spray channel, thus dyeing the fabric.

[0039] Preferably, the nozzle core is mounted on the support base 73 and fixed inside the nozzle housing 7 by the limiting plate 8. The bottom of the nozzle core is connected to the support base 73, that is, the nozzle core is placed on the support base 73 and connected to the top of the support base 73. The limiting plate 8 is fixedly connected to the nozzle housing 7, and the limiting plate 8 covers the top surface of the nozzle core, thereby limiting the nozzle core and preventing it from detaching from the nozzle housing. The nozzle core and the nozzle housing are fixed together, which has a simple structure and is easy to install. It also eliminates the need for welding or applying force to fix the nozzle core, thus avoiding affecting the accuracy of the liquid spraying channel.

[0040] Accordingly, see Figure 2-5 This utility model also discloses a dyeing machine, which is equipped with the above-mentioned nozzle. The specific structure of the nozzle is as described above and will not be repeated here.

[0041] In summary, this utility model provides a nozzle and a dyeing machine with uniform spray channel, high precision, uniform spray force, and good dyeing effect.

[0042] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
